Where is this data available? I would like to see the data to show the 18 point drop for Mexico in August (so I assume you would compare it to a July run).

I would also like to see the US numbers as well.

Is this all the data that they use in the FIFA rankings? I was under the assumption that the algorithm was not public.

Here's the explanation:

First of all, we do live in different time zones, that's why I'm a bit late in answering.The algorithm is public. As Foosinho said look at this pdf file - you'll get all the details -> Calculation of points.While I don't have the time right now to post the data for Mexico's 13 places (not 18 points!) drop or the US values, I hope you'll trust my blog for this.I announced on July 3rd that Mexico will drop to 32nd, one spot below the US -> link.On August 8th I said Mexico will overtake the US with a home win against Honduras -> link.And on August 21st, I posted a preview of the September FIFA Rankings with Mexico on 24th -> link.If you think I somehow changed the dates of the posts on my blog in order to look smart, check the FIFA Ranking thread on BigSoccer.The FIFA Rankings are indeed flawed, I never said otherwise.

If that isn't enough for you, I will try to find the time to post the detailed point totals for US and Mexico for July and August 2008.
